BLOGPOST: NIST lists three cloud service models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) (please see the "As discussed in the Defining Cloud Computing" post and Figure 1).

BLOGPOST: Understanding cloud security risks is related to understanding the relationships and dependencies between cloud computing models. IaaS forms the foundation of the service model architecture, PaaS builds upon IaaS, and SaaS in turn builds upon PaaS; and information security issues and risks are inherited just as capabilities are.

BLOGPOST: Interoperability and portability are closely related to the previously discussed Cloud elasticity and multi-tenancy. Any IaaS to SaaS cloud-implemented system should have as design goals both interoperability and portability to fully gain the benefits of the Cloud elastic environment. Although interoperability and portability are not unique for cloud and the related security aspects did not emerge with cloud computing, multi-tenancy (where data and applications of different customers/companies share platforms, storage, networks) brings the need of greater precautions than those required for traditional processing models.

BLOGPOST: Being locked-in by a cloud provider is not what customers plan to experience. So, let’s explore a bit more on the cloud portability and interoperability topic. The Open Cloud Manifesto explains data and applications interoperability and portability

BLOGPOST: Clouds today do not interoperate, resulting in absolute limitations in geographical coverage, resource functionality, and resource scalability. A cloud provider may not have resources where a cloud consumer needs them; a cloud provider may not offer the type of resource needed; and a cloud provider's resources cannot be infinitely elastic.

BLOGPOST: Cloud computing has huge potential to accelerate research, enhance collaboration, and enrich education. Educators, research administrators, IT directors, and research should realize and leverage cloud’s potential in research, teaching, and learning. They can complement their current in-house cyberinfrastructure by deploying public, private, or hybrid clouds. In fact, as a recent survey reveals, some are already benefiting by embracing the clouds.

PODCAST: Cloud computing is no longer on the horizon; it’s already here in a big way. Governments, business, industry, and individuals are increasingly using cloud computing for their information processing, and computational and developmental needs. They have begun to realize several benefits of cloud computing, including pay for the use, quick deployment of applications, variety of offerings from several cloud service providers, enhanced collaboration, agility, scalability, and availability.

BLOGPOST: This week, I had the honor of co-hosting the “Future of Mobility and its Impact to Cloud” breakout session at The Intersection of Cloud and Mobility Forum, which attracted more than 50 government and business experts in the fields of cloud, mobility, and measurement. Here I share some of my presentation main points, and the brainstorming questions. >>> Wearables, Scannables, Drivables, Flyables: Did your pill just call you?—Don’t be surprised! It all is coming in full speed. We will be able to monitor our health through wearables, get our houses on the phone, use the human body for data transmission, and sense the environment.
